1 Claim. (Cl. 21120) This invention relates to germicidal deodorizers,and more particularly to a combined mercury vapor germkilling ray lampand germicide vaporizing deodorizer.

It is an object of the present invention to provide a combinedultra-violet lamp and germicide vaporizing deodorizer employing a commonfan for drawing the air past the ultra-violet ray lamp thereby purifyingthe unclean air and immediately thereafter before it is again subjectedto the surrounding space and within a confined chamber and while underthe pressure of the fan, treating the ozone produced air with vaporizingliquids having triethylene glycol, so that the cleaned and germicidetreated air will be taken great distances from the deodorizer and willthereby efiect dual treatment of the air to remove it of offensive odorsand from the smell of ozone which has a smell objectionable to somepeople.

It is another object of the invention to provide a deodorizer employinga vaporing device usable in connection with ultra-violet ray lamp whichcan be controlled to permit more or less of the germicide to beevaporated and to thereby allow the operator to control the amount ofthe germicide which is dispensed into the room and wherein access can behad to the container and wick having the germicide for the purpose ofmaking possible the easy refilling of the container and the conditioningof the wick.

It is still another object of the invention to provide a combinedultra-violet lamp and germicide deodorizer in which the lamp, the motorand fan, the germicide container and the ballast or transformer arearranged in a single container so that the air is. drawn downwardly bythe fan over the lamp and forced immediately upon leaving the lampdownwardly over the vaporizing unit.

Other objects of the invention are to provide a combined ultra-violetlamp and germicide deodorizer having the above objects in mind, which isof simple construction, inexpensive to manufacture and operate, highlyeflicient and effective in use, has a minimum number of parts, has atranslucent crown through which the rays of the lamp may penetrate toindicate that the deodorizer is in operation and to give the same apleasing appearance, easily installed upon a wall surface high enough tobe out of the way of the occupant of the room, durable and will havelong life.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconnection with the accompanying drawing in which:

Figure 1 is a top perspective view of the combined ultra-violet ray lampand germicide vapor deodorizing unit embodying the features of thepresent invention;

Fig. 2 is an enlarged vertical sectional view taken on line 2-2 of Fig.1 with the deodorizer shown mounted upon a wall surface;

Fig. 3 is a perspective view of the lamp mounting within the top of thecylinder housing;

Fig. 4 is a fragmentary sectional view taken on line Patented July 17,1956 4-4 of Fig. 2- and looking upon the top edge of the mountingbracket;

Fig. 5 is a perspective view of the finger grip support for thegermicide container removed from the bottom cap to which the same isattached when mounted into the cylinder housing;

Fig. 6 is a fragmentary top perspective view of the germicide vaporizingwick and container showing the adjustable member for the wick extendinglaterally therefrom.

Referring now to the figures, 10 represents a cylinder housing formed ofsuitable material and open on both the upper and lower ends thereof. Alaterally extending attaching bracket 11 is connected by its arcuateportion 12 at the side of the cylinder housing 10 and has portions 13and 14 to which screws may be extended for securement of the deodorizer.to the wall surface. This cylinder housing is held in an upright manneron the wall so that air can be passed downwardly therethrough from thetop and outwardly from the bottom.

Fitted on the top end of the cylinder housing 10 is a translucentplastic and colorful crown 17, generally circular in shape and extendingoutwardly from the front of the housing but cut away at the rear thereofat 16. This crown 17 also has a depending attaching portion 18 toconveniently fit within the open upper end of the cyltightened secureupwardly bent ends 25 and 26 respectively of the bracket 21 to the topof the cylinder housing. 1

On this bracket 21 there is mounted a lamp socket 26 by means offastening screws 27. A screw 28 serves as a terminal .to which wire 29is attached. Another wire 30 is attached to another terminal at the rearof the socket 26" to provide the other connection for the lamp bulb.

In this socket there is useda germicidal ultra-violet and ozoneproducing lamp v bulb 31 developed for use in room 5 parts a clean,outdoor smell to the air treated by the lamp. Any air treated with thelamp rays becomes effectively sterilized and forced draft induced by thefan delivers clean ozone bearing air into the room. Some people' canstand the smell. of the ozone while others object to it, and accordinglyany use of the lamp by iself in places where the air is to be breathedby the occupants has been objectionable.

While a single lamp bulb 31 is shown, it will be understood that the twolamp bulbs would easily be mounted on the bracket 21 by employinganother socket 26' and making the appropriate wire connections with anelectric energizing source.

Also, mounted in the space within the attaching portion 18 of the crown17 and in the upper end of the cylinder housing 10 and by the same bolts19 and 20, is a fluorescent lamp ballast 32 which may be removed withthe bracket, lamp and socket, and fan from the top of the housing as acomplete unit. Bifurcated end portions 33 are provided on the ballast 32for receiving the bolts 19 and 20. This ballast has wires 34 and 35extending therefrom and connected to the power source. Cable cord 36extends out of the housing by way of a bushing 37 and has a plug 38 bywhich it is attached toan ordinary wall or electric receptacle. Thiscord has a wire 39 connected with an electric motor 40 fixed by means ofa screw 41 to the bracket 21 at hole opening-41 Fig; 3. The motor 40drives a fan 42 that servesto draw air downwardly throughthe'cylinder-housing and overthe ultra-violet lamp 31- so that this airis treated by the lamp and is moved under pressure ofthefan 42downwardly through the housing and toward and over a vaporizing unit 43having a container 44 filled withthe liquid bearing triethylene glycoland a wick adjusting mechanism 45 from which a wick 46 extends to drawthe liquid out of the container and to make it available to the lamptreatedair which is being moved downwardly through the cylinder housing10. This lamp treated air is accordingly made a carrier for thegermicide dispensed by the vaporizing unit 43 so that the germieid'e iscarried by this air to locations removed from the deodorizer.

A special finger projecting; bracket 47 having finger projections 48, 49andSO, Fig. 5, and; a handle projection 51 receives the container 44 andholds the same against displacement Within the cylinder housing. Thisbracket 47 has an opening 52 in the bottom thereof 'by which it is fixedby a grommet 53 to a bottom perforated cap 54 having perforations 55andwhich is fixed to the lower end of the cylinder housing It will benoted that both the vaporizing unit and thelarnp 31 are olfset frommotor 40 of the fan blade 42 so that an unimpeded induced draft from thecentrally located fan blade 42 can be had. It will thus be seen that thelamp treated air is immediately treated with the liquid from thevaporizing unit so that any ozone produced will be overcome by the sweetsmell of the vaporizing germicidal bearing liquid. The liquid can haveany of'the wellknown fragrances, such as pine, fruit, spearmint, or-suchother well known fragrances which are available.

The wick mechanism 45 has a turn shaft 56 which extends through anopening 57 in the side wall of the housing and to which there isattached'at its outer end a turn knob 58 by means of a set screw 59.With the knob 58' removed, the shaft 56 can be, easily drawn through theopening 57 and the vaporizing unit removedas the cap 54 with thevaporizing unit 43 is fixed-.to. the end of the housing or removedtherefrom. It will thus be seen that the vaporizing unitiseasilyaccessible. so that the container 44 can be refilled with thevaporizing liquid.

The translucent plastic crown 17 is so shaped to. direct easily the airto the cylinderjhousing and on the lamp being energized so that lightrays pass, outwardly thereof, this crown is illuminatedin a mannersothat the operation of the deodorizerwill be indicated; so as-to givethe deodorizer a pleasing appearance. It should now be apparent thatthere has been provided a highly efiective deodorizer employing bothalamp and a vaporizing unit in a single cylinder housing and'a fan forforcibly. moving the air through the housingandjn such a manner that itis drawn downwardly over the lamp. and forced outwardly over thevaporizing unit;

While various changes may be made in the detailed construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.
